Abstract
A high input impedance switched capacitor amplifier is disclosed. The switched capacitor amplifier includes at least a first buffer circuit configured to charge a first plurality of capacitors during a first time period. A switch circuit is configured to, during a second time period, cause a modification of an amount of charge stored on one of the first plurality of capacitors by coupling an input signal directly to the one of first plurality of capacitors. An amplifier circuit is configured to, based on a sampling voltage present on one of the first plurality of capacitors, generate an output signal.
